a. An LOA or LOP is required on many occasions when complying with this regulation. All such letters will be coordinated with the appropriate DARR during the development stage or when being modified. Copies of the final version of these letters will be forwarded to the appropriate DARR. Units operating in host countries will coordinate each LOA or LOP with USAASDE, ATC coordinator (Korea), or the MACOM AT&A officer.
b. Each LOA or LOP will be reviewed at least once each year. The DARR, USAASDE, ATC coordinator (Korea), or MACOM AT&A officer will participate in these reviews.
